2008 Cadillac CTS 4dr Sedan w/Direct Injection (3.6L 6cyl 6A)
This vehicle guzzles gas worse than an SUV. Don't be fooled. It doesn't get anywhere near the 18 city/26 highway. I'm currently getting around 16 MPG in mostly highway driving. The vehicle has an 18 gallon tank that will only take you around 230 miles. Don't buy or lease this car if you are concerned about the environment or your own vehicle ownership costs!
